Rapid bearing replacement · Cost savings · Application examples Rapid bearing replacement at difficult to access locations Split spherical roller bearings are principally used where the replacement of unsplit spherical roller bearings would require costly additional work, involving the removal of gears or couplings, the dismounting of drives or the dismantling of shaft power trains. The use of split spherical roller bearings reduces the downtime of machinery and plant. Application examples Split spherical roller bearings are essentially used on shafts supported at several points and...

Application examples Application examples in the pulp and paper industry: • Fans and ventilators • Mixing and stirring plant • Dryer rolls • Drive and transmission shafts • Conveying equipment • Comminution machinery Shaft bearing arrangements in mixing and stirring plant Drive bearing arrangements in conveying and transport equipment Bearing arrangements in fans and ventilators Fitting of a large split spherical roller bearing

Replacement for bearings with adapter sleeve · Fitting in split plummer block housings Replacement for bearings with adapter sleeve Split spherical roller bearings can generally be fitted instead of unsplit spherical roller bearings with adapter sleeves. The precon dition for replacement is that the outside diameter, outer ring width and diameter of the shaft seat are identical, see Product range, page 5. Fitting in split plummer block housings Split spherical roller bearings can be fitted in our split plummer block housings without additional machining of the housings. This also applies to...

Product range · Bearing design Product range Bearing design Our comprehensive range contains split spherical roller bearings for metric shaft diameters from 55 mm to 630 mm and inch shaft diameters from 2 D/bg inch to 16 inch. Split spherical roller bearings have a cylindrical bore. The inner ring, outer ring and cage with the roller set are split in half. The split bearing rings are held together by screws. In most cases, the outside diameter, outer ring width and diameter of the shaft seat are identical to those of standard spherical roller bearings of series 222, 230, 231, 239, 240 and...

Load carrying capacity · Speed suitability · Fits · Lubrication Load carrying capacity The load carrying capacity of split spherical roller bearings is lower than that of unsplit spherical roller bearings, since the pitch circle for the rolling element set is smaller due to the screw connection in the outer ring. Nevertheless, they can achieve a high load carrying capacity since they have the maximum number of rollers with the largest possible dimensions (E1 design). The overrolling of the joints is taken into consideration in calculation of the equivalent dynamic load by applying the shock...

Fitting of split spherical roller bearings 1 Support the weight of the rotor 2 Remove the housing cover 3 Dismount the old bearing (unsplit bearings with adapter sleeve should be carefully cut through using a parting-off grinder) 4 Place the outer ring half in the lower section of the housing and align it with the inner ring mounted on the shaft, then screw together the inner ring halves 5 Fit the remaining parts, finishing with the upper outer ring half 6 Lower the shaft in order to subject the bearing to load 7 Fit the upper section of the housing The following pictures give a summary of...
